I will place a conical flask on top of a sheet of white paper with a black cross of ink in the centre . The reactants will then be added to the flask ( see table below ). A total of 70 cm of reactants will be used each time (50 cm of Sodium thiosulphate and 20 cm of HCl ) , this will keep the depth of the solution the same each time so that the optical properties of the liquid to not change . Using a burette to make up the desired concentration of sodium thiosulphate diluting with distilled...
